CVE-2026-42295
Description
A flaw was found in Argo Workflows, an open source container-native workflow engine for orchestrating parallel jobs on Kubernetes. The workflow executor logs all artifact repository credentials, such as S3 (Simple Storage Service) access keys, GCS (Google Cloud Storage) service account keys, Azure account keys, and Git passwords, in plaintext during artifact operations. This allows any user with read access to workflow pod logs to extract these sensitive credentials, leading to information disclosure.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Access Control
Technical Impact: Gain Privileges or Assume Identity
Storing a plaintext password in a configuration file allows anyone who can read the file to access the password-protected resource. In some contexts, even storage of a plaintext password in memory is considered a security risk if the password is not cleared immediately after it is used.
